Relative dynamic digital delay can be used to program a clock output to a specific phase offset from another clock output.
Pros:
- Direct phase adjustment with respect to same clock output.
- Possible glitch pulses from clock output will always be the same during digital delay adjustment transient.
Cons:
- For some clock divide values there may be a glitch pulse due to SYNC assertion.
- Adjustments of digital delay requiring the half step bit (CLKout12_13_HS) for finer digital delay adjust is complicated due to the half step requirement in Table 9-5 above.
